Semiautomatic Treatment Planning for the Field-in-field Technique in Whole Brain Irradiation

Objectives In radiation therapy, the field-in-field (FIF) technique is used to prevent administration of unnecessarily high doses reduce toxicity. Recently, FIF has been for whole brain irradiation (WBI). Using technique, volume that receives a higher than prescribed dose (hotspot) can be largely reduced; however, treatment planning requires time. Therefore, burden on planners, we propose semiautomatic method technique.
